Wifi adapter does not work after dnf update

This week-end I updated my Fedora 31 from :
[uname -r]

5.6.16-200.fc31.x86_64
to
5.7.7-100.fc31.x86_64

My wifi adapter is found in both cases :
[lsusb]
Bus 001 Device 004: ID 0846:9030 NetGear, Inc. WNA1100 Wireless-N 150 [Atheros AR9271]

But initialization now fails :

[dmesg | grep -i ath9k]

/!\ KO /!\

Can you help me to fix that issue please ? Many thanks.

Hello @franchips, and welcome to the community. When you have a moment, please take a look at the #start-here category.

Unfortunately, that is a bug in the current kernel (see below for more info). A fix is known and will hopefully find it’s way into Fedora soon. In the meantime, do you still have a kernel older than 5.6.19 installed on your system? If so, boot from that until the fix lands.

OK so wait & see.

Thank you for your help :slight_smile:

Yeah, unfortunately nothing else to be done. Hopefully it won’t take too long.

Hello, do you know if we have any progress about the wifi usb adapter bug please ? Thank you.

Hi, did you check the topic I linked? The bug has been fixed in 5.7.9, which has made its way into Fedora 32. So if you update to the latest kernel packages, your adapter should work again.

My mistake, I was on 5.7.9 but I didn’t unplug/plug the USB wifi adapter… It works now. Thank you for your support.

Great, glad it works!

I am currently experiencing this same problem on fedora 32, reverted to kernel version-5.6.6-300.fc32.x86_64 as a temporary fix. Is it safe to run dnf update now ?

Yes - by all reports, 5.7.9 fixed the problem.

By the way: It is always safe to update, because while older kernels normally will be automatically removed, dnf won’t ever remove the running kernel, i.e. if you booted your 5.6.6 kernel, that package is kept no matter how many newer versions come out.

Great good to know fedora keeps the running kernel, thanks. The update actually installed kernel-5.7.10-201.fc32.x86_64 for me, no complaints thus far

Yeah, that update got pushed to the stable repositories a couple of hours ago.
